modelConstantEfficiency
Efficiency model considering constant efficiency
Extends from Modelica.Mechanics.Rotational.Interfaces.PartialElementaryTwoFlangesAndSupport2 (Partial model for a component with two rotational 1-dim. shaft flanges and a support used for textual modeling, i.e., for elementary models), Modelica.Thermal.HeatTransfer.Interfaces.PartialElementaryConditionalHeatPortWithoutT (Partial model to include a conditional HeatPort in order to dissipate losses, used for textual modeling, i.e., for elementary models).
Information
Model of constant efficiency independent of speed and torque.
